[UX advise] Key navigation in ValueSet controls

I see.

This again makes lots of sense to me. Also, we didn't hear anything
about wrapping around from top to bottom being necessary behaviour, so
I guess, just doing it should be fine.

As I said, I /think/ you should keep that behaviour.

Hrm. Extremely wild idea: use backspace..?
More conventional idea: use Tab to go the normal items, use Shift-Tab
to go to the "None" item.

I just noticed that wrote that this is used for both both colour
configuration and selection ...
* for the configuration what I wrote makes sense
* for selection, less so – I guess, pressing Return there should
indeed close the popup
